(Federation of American Societies for Experimental Biology) New research findings published in the Journal of Leukocyte Biology (http://www.jleukbio.org), suggest that treating the white blood cells of sepsis patients with antibodies that block programmed cell death-1 (PD-1) and programmed cell death ligand (PD-L1) molecules may restore their function and ultimately their ability to eradicate deadly bacteria.
